Key Points to Consider When Choosing an Ergonomic Chair

While there is a wealth of comprehensive information online about ergonomic chairs, I'd like to share a few key points based on my personal experience:

Base The base of an ergonomic chair is arguably the most telling feature of a manufacturer's technical expertise. The base can be considered the "heart" of the chair; a quality base provides good feedback to the body, and comfort largely depends on it. Common types of bases on the market, from low-end to high-end, include single torsion springs, single compression springs, dual compression springs, and dual fiberglass bases. Few manufacturers can produce a dual fiberglass base; aside from well-known brands like Herman Miller, the domestic product Xihao S300 features a dual fiberglass base. This type of base offers precise elasticity, excellent flexibility, a large range of motion, and a long lifespan, which distinguishes it from traditional base designs.

Support The primary function of an ergonomic chair is to provide support. Good support helps maintain proper sitting posture, while improper sitting over time can lead to health issues such as lumbar, cervical, and spinal problems, as well as poor blood circulation. Support is mainly focused on the lower back and back, but support for the arms, hips, and legs can also alleviate muscle pressure. The quality of support is the result of multiple factors, including structural design, materials, and adjustable features (like lumbar support adjustments and seat height adjustments). If you have existing lumbar issues, make sure to assess whether the chair provides adequate support—weak support means you've essentially bought a chair that won't help.

Size The issue of size cannot be overlooked! Not all chairs fit every body type; mismatched sizes can lead to discomfort. A chair that is too small will feel cramped, while one that is too large won't provide the necessary fit. For example, a shorter person sitting in a chair with a high backrest and limited adjustment range may find that their neck rests on the back without reaching the headrest. To determine if the size is appropriate, consider the following dimensions: seat height (typically adjustable via a gas lift to accommodate most people), seat width, seat depth (ideally leaving about a fist's width between the back of the knees and the edge of the seat), and backrest height. It's especially important to inquire about dimensions for non-adjustable features.
